Backward Compatibility
The USB 3.0 Type-A interface maintains backward compatibility with USB 2.0 and 1.1 ports, allowing the adapter to function on older systems, albeit at reduced network speeds appropriate for the host port's capability.
Deployment / Use Cases
The USB31000S2 adapter is engineered for scenarios where reliable, high-speed wired connectivity is critical but not natively available on the host device. It serves as a vital tool for maintaining network performance and stability in dynamic IT environments.
Common deployment scenarios include equipping ultra-thin laptops and tablets that sacrifice Ethernet ports for slim designs, providing a stable connection for VoIP or video conferencing applications where Wi-Fi latency is problematic, and serving as a temporary network interface during desktop PC repairs or motherboard replacements. It is also widely used in point-of-sale systems, kiosks, or industrial PCs where a wired connection is mandated for security or reliability.
Physical Profile
The adapter presents a sleek, low-profile design measuring 7.70" in height (including the integrated cable), 0.60" in width, and 0.90" in depth. Its Space Gray color and smooth finish provide a professional aesthetic. Weighing a mere 0.50 oz, it adds negligible bulk to a laptop bag. The form factor is specifically designed to be portable and unobtrusive, whether plugged directly into a laptop side port or connected via its short cable to sit neatly on a desk.

User Manual
FAQ
What operating systems are compatible with this USB Ethernet adapter?
The adapter offers extensive plug-and-play compatibility. It is supported natively by Windows 7, 8, 10, 11, and Windows Server editions. It also works with macOS 10.14 and later, many Linux distributions with kernel versions 4.11 to 5.9.16 LTS, and Chrome OS. This wide coverage makes it suitable for mixed-IT environments.
Does this adapter require external power or drivers?
No external power adapter is needed; the device is entirely bus-powered through the USB port. For most modern operating systems listed, it functions as a plug-and-play device with native driver support. In some cases, especially with older Windows versions, you may need to download a driver from the manufacturer's website, which is included in the support documentation.
What is the maximum network speed this adapter supports?
This is a Gigabit Ethernet adapter, supporting the full 10/100/1000 Mbps (1 Gbps) standard over twisted-pair cabling. The USB 3.2 Gen 1 host interface provides a 5 Gbit/s data pipeline, ensuring the adapter does not bottleneck the Gigabit network connection.
Can I use this adapter on a computer with only USB 2.0 ports?
Yes, the USB Type-A interface is backward compatible with USB 2.0 and 1.1 ports. When connected to a USB 2.0 port, the adapter will still function, but the maximum network speed will be limited by the bandwidth of the USB 2.0 bus, typically supporting up to Fast Ethernet (100 Mbps) speeds effectively.
What is the length of the attached cable, and can it be detached?
The adapter has a permanently attached USB cable that is 1 foot (approximately 30 cm or 11.8 inches) long. This cable is not detachable or replaceable. The integrated design enhances durability and ensures you always have the necessary cable, making the unit a single, compact package.
What warranty and support does StarTech.com provide for this product?
StarTech.com backs the USB31000S2 adapter with a 2-year limited warranty, covering defects in materials and workmanship. Additionally, they offer free lifetime 24/5 technical assistance (Monday-Friday, 24 hours a day), providing valuable support for installation, configuration, and troubleshooting throughout the product's lifecycle.
